Dating in the internet age is rife with complications, and yet Dave Simpson’s amiable romcom manages to eschew nearly all of them. Bar its online matchmaking set-up, this is a chaste, big-hearted time capsule of a play, with nary a glance at Facebook or Twitter, let alone the ephemeral intimacies of Tinder and Snapchat. Simpson’s old-fashioned piece is a perfect partner to his resolutely gauche paramours, but, over an almost two-hour running time, offers curiously nebulous commentary on contemporary romance.
